Anti-CHPF antibodies are used in the immunodetection of the protein chondroitin polymerizing factor. In humans, the canonical protein has a reported length of 775 amino acid residues and a mass of 85.5 kDa. Its subcellular localization is in the mitochondria, Golgi, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Chondroitin N-acetylgalactosaminyltransferase protein family, CHPF is known to have both beta-1,3-glucuronic acid and beta-1,4-N-acetylgalactosamine transferase activity. Synonyms for this target antigen include N-acetylgalactosaminyl-proteoglycan 3-beta-glucuronosyltransferase II, N-acetylgalactosaminyltransferase 2, chondroitin glucuronyltransferase 2, and chondroitin sulfate synthase 2. CHPF gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of CHPF antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
